A. Our favorite items to pack along for chilly evenings are shrunken cardigans and lightweight scarves. Both roll up into small packages to tuck into a handbag or tote and work with everything from tanks, tees and feminine tops to dresses. Unless your work cardigans are boxy, they should pair perfectly with your more casual clothes - just open up the buttons and push up the sleeves a bit. As for jackets, everything from shrunken boyfriend styles to slouchy unstructured blazers work well.
